The typesetting was not a problem -- all handled by LibreOffice Math. It was easier than writing.

I agree, it's a general solution to a specific set of equations :) Thanks, I thought that there was a simpler way of solving those.

I herewith submit for reference, review and comment the general solution to 3 simultaneous equations as follows:

OK, I suspected that it can't be further simplified as well, I was just asking. It would have made subsequent calculations less complex.

Can anyone simply this equation? Alternatively is there a website where I can simplify formulas?

What you say is true, I probably haven't sufficiently explained myself... f' can be eliminated by conservation of momentum as shown above. b' can be eliminated with this approximation b' = b + eδt. Now I could obtain e' by a similar approximation but that would result in energy not being...

Yes that is what I am talking about. My system is a computer simulation similar to those that I have posted previously; the objects are obviously not actually physical objects but like physical objects . The objects obey Newton's laws of motion and gravitation; if they happen to collide then...

What I meant by invoking the term "state system" is a system that consists of a set of well defined states. This system consists of the following vector attributes b,c,e,f the components of which may take on the numbers representable by my computer. That is there is no quantum fuzzyness or real...

I am treating the two body system as a state system. b, c, b', c', e, f, mb, mc are all known. Though b' and c' are calculated by approximation according to the equation b' = b + eδt. Hope this clarifies what I am trying to achieve. I suspect that by quantizing δt I will not be able to...

Thanks Drakkith, yes I have done that already but now I would like the simulation to conserve energy. This simulation does not conserve energy: This simulation does conserve energy but there is no orthogonal velocity component. Still not sure how to solve the above equation. Should I look at...

Yes, because they can be calculated according to b' = b + eδt.

So should I break down e, e' and f into their components?

I'm working on a computer graphics program that simulates the motion of two point masses as indicated in this diagram: After applying the laws of conservation of momentum and the conservation of energy I am left with the following equation to solve for e': Does anyone have any idea how to...

Fair enough. So my follow up question is does the half-life of a particular isotope vary in accordance with any other physical property such as electric field - excepting weak nuclear force which you have mentioned.

Would the observed half-life of a sample of a radioactive isotope (eg. iodine 131) be different from the nominal half-life when it is cooled down to a temperature near absolute zero. Have there been any experiments conducted to examine this question?
